I think this is a very interesting photo! You might consider cropping the bottom where it turns dark though and do away with that font. I have a hard time reading it, and it intentionally lists to the right, which doesn't help it. Play around with the cropping from the bottom, maybe you'll find a square crop better, and it will be easier for your font too.

Is this a thriller/mystery type of book? Maybe you might browse amazon's book selection for ideas on font selection and placement: http://www.amazon.com/Mystery-Thrillers-Books/b/ref=bhp_bb0309A_mysthr2?ie=UTF8&node=18&pf_rd_m=ATVPDKIKX0DER&pf_rd_s=browse&pf_rd_r=0DR6BQMH044VBAE9NPDB&pf_rd_t=101&pf_rd_p=471987351&pf_rd_i=283155
I also typed in "secret" and came up with this list: http://www.amazon.com/s/ref=nb_ss_b?url=node%3D1000%2C18&field-keywords=secret&x=0&y=0
Anyway, I really like this photo, so I hope that was helpful.
